BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a solar collector, and more particularly to a closable solar collector that is convenient to store and transport.

2. Description of the Prior Arts

A solar collector is a device for collecting energy from the sun direct use or storage. A conventional solar collector comprises at least one solar panel mounted securely on a frame and mounted in a place facing the sky like a roof, or a square other altitudes. The solar panel has multiple solar cells mounted securely on the solar panel to form an absorbing surface. The absorbing surface absorbs solar energy striking the absorbing surface and transformed solar energy into electricity for commercial and residential applications. The absorbing surface with a larger surface area absorbs more solar energy to result in more power being provided by the solar collector.

However, the absorbing surface with a larger surface area is difficult to transport and store. Besides, the absorbing surface is exposed all the time and consequently covering or storing the solar panel during the sudden onset of a typhoon, rain or snow may be difficult or impossible, which could easily lead to the absorbing surface being damaged.

To overcome the shortcomings, the present invention provides a closable solar collector to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a closable solar collector that is convenient to transport and store.

To achieve the objective, the closable solar collector in accordance with present invention comprises a stand, a solar panel body, a ball screw and a linking assembly. The solar panel body is mounted on the stand and has a base solar panel, multiple side solar panels and multiple folding solar panels. The side solar panels are mounted pivotally around the base solar panel. Every two folding solar panels are mounted pivotally between two adjacent side solar panels. The ball screw is mounted through the base solar panel and has a nut. The linking assembly is mounted pivotally between the nut and the stand and has multiple upper linking rods and multiple lower linking rods. Each lower linking rod has a top end mounted slidably between two adjacent folding solar panels. The ball screw is actuated to drive the linking assembly and the solar panel body to move so the solar panel body can be open or closed. Therefore, the solar collector is convenient and easy to use and store.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The linking assembly (40) is mounted pivotally between the nut (32) and the stand (10) and has multiple upper linking rods (41), multiple lower linking rods (42), a cover (43) and multiple sleeves (44). The upper linking rods (41) are mounted radially around the threaded shaft (31) and each upper linking rod (41) has a top end and a bottom end. Each lower linking rod (42) is mounted pivotally on the bottom end of a corresponding upper linking rod (41), mounted movably through a corresponding slot (212) of the base solar panel (21) and has a top end and a bottom end. The bottom ends of the lower linking rods (42) are mounted pivotally on the board (11) around the central hole (111) of the board (11) of the stand (10). The cover (43) is mounted pivotally on the top ends of the upper linking rods (41) and mounted securely on the nut (32) and has a hole and multiple sides. The hole of the cover (43) is mounted around the threaded shaft (31). The sides of the cover (43) respectively correspond to top edges of the top solar panels (24). Each sleeve (44) is mounted pivotally on the top end of a corresponding lower linking rod (42) and mounted slidably around a corresponding rod (25B).

In a preferred embodiment, the base solar panel (21) is hexagonal and has six sides, each side is connected pivotally to a corresponding side solar panel (22) and the side solar panel (22) is rectangular. The folding solar panels (23) are triangle and every two folding solar panels (23) are mounted pivotally between two adjacent side solar panels (22). The linking assembly (40) has six upper linking rods (41) and six lower linking rods (42). The top solar panels (24) are trapezoidal, the cover (43) is hexagonal and has six sides respectively correspond to top edges of the top solar panels (24).

With reference to FIG. 5, the threaded shaft (31) is powered by the motor (50) or manpower and the nut (32) and the cover (43) move along the threaded shaft (31) upwards and drive the upper and lower linking rods (41,42) to move. When the upper and lower linking rods (41,42) moves toward the threaded shaft (31), the folding solar panels (23) and the side solar panels (22) are pulled to fold. With further reference to FIG. 3, the side pivots (25) between the folding solar panels (23) and the side solar panels (22) rotate so the side bevel gears (27) rotate as well and drive the top bevel gears (27A) to rotate and allow the top solar panels (24) to close synchronously.

When the nut (32) and the cover (43) move along the threaded shaft (31) downwards and drive the upper and lower linking rods (41,42) to move. The solar panels (21.22.23.24) is expanded and located in a same plane to allows absorbing surfaces of the solar panels (21,22,23,24) to face up and absorb solar energy.

With reference to FIGS. 6 and 7, the solar panel body (20) is closed. The top edges of the top solar panels (24) abut the sides of the cover (43). The side solar panels (23) is in an upright state to form a hexagonal prism and a chamber inside the hexagonal prism. Every two adjacent folding solar panels (23) are close to each other and in the chamber. An area of the closed solar panel body (20) is smaller than an area of the open solar panel body (20) so the solar collector with the closed solar panel body (20) is convenient to transfer and store. Besides, the closed solar panel body (20) allows the absorbing surfaces of the solar panels (21,22,23,24) to face inside and prevents damage.
